1 . The maleo (塚雉), a bird with black feathers and a pink chest, is native to Indonesia’s Sulawesi island and a few neighboring ones. The International Union for Conservation of Nature (IUCN), which identifies wildlife across the world currently facing threats, estimates only 800 to 1,400 adult maleos remain in the wild. Experts do not know how many maleos still live across West Sulawesi island. They were only able to record the presence of nesting grounds in 23 villages based on reports from locals in the area. But of those, only 18 are considered active nesting areas.
Recently, the birds have been faced with new threats, which accelerate their decline. The Indonesian government plans to move the nation’s capital from Jakarta to a new city on Borneo island, which is just a six-hour boat trip apart from Sulawesi island. The island takes on the building of new roads and seaports to be used to transport materials to the new capital. Activities also include tree clearing, digging, and removing stones. The process already has changed the forest environment on West Sulawesi and is harming maleo nesting areas near the beach. These changes have made the trip for maleos to lay their eggs increasingly difficult.
Another problem has been poachers. The Associated Press reports that, regardless of official ban, they steal maleo eggs that the males’ parents have hidden in the sand, and sell the eggs for about $1 to people as food. The eggs are a traditional gift for many people in Mamuju and other parts of Sulawesi.
“As far as I know, maleo birds are in decline,” said Andi Aco Takdir, chief of the West Sulawesi Forestry Agency. He pointed to several reasons for the decline, including destruction of beach areas, and expanding human development activities. He added that government officials there are prepared to take steps to protect the maleos even with the new capital development. Andi said, “Nature conservation must be used as an achievement and must not be built leaving behind problems.”

2 . Sara Dykman is on a 10, 000-mile bike trip, following the monarch butterfly from Mexico through the UnitedStates and Canada and back again. The purpose of her journey is not just to mark the butterfly’s migrating (迁徙) road, but to warn about the threat it faces — and what we can do to help it.
When I reached Dykman by phone, she was biking through Iowa cornfields. She said she feels more upset than usual, because of what she is seeing — or not seeing — on her travels: Fewer butterflies and milkweed. “In the last two decades, the butterfly population has declined by about 90 percent as a result of the loss of milkweed, a native plant that the butterflies need as part of their life cycle,” she said.
Butterflies go through a four-stage life cycle. In February and March, the adult monarch butterflies come out of winter sleep to look for a mate. Then they migrate north and east to lay their eggs on milkweed plants. It takes about four days for the eggs to hatch. Then the baby caterpillars (毛毛虫) spend much of their time eating milkweed in order to grow. About two weeks later, the fully grown caterpillars will attach themselves to plant branches or leaves to change into butterflies.
But Dykman is not in total despair. A solution, she says, exists within the reach of everyone who owns a home; simply planting some milkweed in the yards to help the butterflies on their journey.
Dykman lives a life as simple and rootless as the butterflies she loves. She doesn’t own a house or car or eat out at restaurants. She carries only what she needs; a sleeping bag and clothing. People help along the way by providing a place to stay and a meal.
“I have failed at everything normal, but I’m pretty good at doing the less normal things,” she admits in her new book Cycling With Butterflies.
“But this trip is about solutions, and it’s about helping people see the consequences of their actions,” she said on the phone.

3 . Humans can make do with scarves, coats and gloves in cold weather. Some animals can hibernate (冬眠) for the winter. A new study finds that reptiles (爬行动物) and birds do something that is similar to hibernation, but a little different. In very cold weather, their body temperatures greatly drop into an energy-saving state in order to survive. The ability to thermoregulation (体温调节) for reptiles and birds is possible.
In Texas, where the city of Beaumont reached a low of 18 degrees Fahrenheit last month, it looked as if alligators (短吻鳄) had died of cold — yet alive in iced-over water. By ensuring their long noses stayed above the water line, the cold-blooded creatures were able to lower their body temperatures to survive the sudden short period of very cold weather. The process, in the case of cold-blooded animals like reptiles, is called brumation — it’s like a short state of hibernating. While in this state, reptiles become sleepy and they can go for a long time without eating or drinking. For example, alligators can be in brumation from just a few hours to months.
Like reptiles and mammals, birds can go into a state called torpor in order to save energy under very cold conditions. “Torpor is somewhere between a short sleep and hibernation,” said Justin Baldwin, a PhD candidate in biology at Washington University in St. Louis. Baldwin studied 29 species of hummingbirds living in Colombia. Researchers found that hummingbirds can enter into deep or shallow torpor, depending on several factors, including their size and weather conditions. In deep torpor, the birds are much more likely to be affected by disease. And what’s more, they would be easily harmed by their enemies.
Some bird lovers want to help the birds when they are in torpor. For example, the Bird Alliance of Oregon offers a few tips on how to keep the birds from danger.

4 . Most of us are familiar with Groundhog Day, wherein a large groundhog checks to see its shadow on February 2 and helps to predict when winter will end. But have you ever heard about how a mountain town in North Carolina uses a caterpillar (毛毛虫) known as the Woolly Worm to make similar predictions?
According to the folklore (民间传说), the amount of black on the woolly worm in autumn predicts the severity of the upcoming winter. The longer the woolly worm’s black bands (带) are, the longer, colder, snowier, and more severe the winter will be. Similarly, a wider middle brown band is associated with a milder upcoming winter. The position of the longest dark bands supposedly indicates which part of winter will be coldest or hardest. If the head end of the caterpillar is dark, the beginning of winter will be severe. If the tail end is dark, the end of winter will be cold. In addition, the woolly worm caterpillar has 13 segments to its body, which traditional forecasters say correspond to the 13 weeks of winter.
Scientific studies on worm forecasting are few and far between. The most often cited is a small trial that American Museum of Natural History entomologist Howard Curran conducted in 1948. Having heard about the caterpillar folklore, Curran traveled to Bear Mountain State Park to collect woolly worms each fall for eight years. He found that if the worms had brown markings on more than a third of their body, winters tended to be milder.
Most scientists discount the folklore of caterpillar predictions as just a folklore. “It’s a wonderful story, but I do think it was a playful trial,” says Joe Boggs, an entomologist at Ohio State University Extension who has studied woolly worms. “Curran was a real scientist. He had a bunch of papers published, but he never published this one—probably because he knew it wouldn’t stand up to peer review.”
Mike Peters, an entomologist at the University of Massachusetts, doesn’t disagree, but he says there could be a link between the band of a woolly worm and the severity of winter. Peters suggests that the timing of their growth and environmental conditions, such as temperature, moisture levels, and food sources, can impact the appearance of woolly worms, including their size, coloration, and band patterns. By analyzing these characteristics, researchers can potentially infer information about the weather conditions. “The band does say something about a heavy winter,” he says. “The only thing is that it’s telling you about the previous year.”
